snowflake-oauth: document where to locate the redirect URI (#5955)

## What are you changing in this pull request and why?

A new copy input has been added to the dbt Cloud UI which allows users
to easily find the redirect URI when setting up Snowflake OAuth. The
documentation has been updated to show users where to locate this value.

 dbt Cloud Enterprise supports [OAuth authentication](https://docs.snowflake.net/manuals/user-guide/oauth-intro.html) with Snowflake. When Snowflake OAuth is enabled, users can authorize their Development credentials using Single Sign On (SSO) via Snowflake rather than submitting a username and password to dbt Cloud. If Snowflake is setup with SSO through a third-party identity provider, developers can use this method to log into Snowflake and authorize the dbt Development credentials without any additional setup.
 
-### Configuring a security integration
-To enable Snowflake OAuth, you will need to create a [security integration](https://docs.snowflake.net/manuals/sql-reference/sql/create-security-integration.html) in Snowflake to manage the OAuth connection between dbt Cloud and Snowflake.
+To set up Snowflake OAuth in dbt Cloud, admins from both are required for the following steps:
+1. [Locate the redirect URI value](#locate-the-redirect-uri-value) in dbt Cloud.
+2. [Create a security integration](#create-a-security-integration) in Snowflake.
+3. [Configure a connection](#configure-a-connection-in-dbt-cloud) in dbt Cloud.
+
+To use Snowflake in the dbt Cloud IDE, all developers must [authenticate with Snowflake](#authorize-developer-credentials) in their profile credentials.
+
+### Locate the redirect URI value
+
+To get started, copy the connection's redirect URI from dbt Cloud:
+1. Navigate to **Account settings**
+1. Select **Projects** and choose a project from the list 
+1. Select the connection to view its details abd set the **OAuth method** to "Snowflake SSO"
+1. Copy the **Redirect URI** for use in later steps
